The focus of the paper is on this latter category, where inputs are varied according to within-paddock spatial variation and spatial information is used to improve decision-making and management... A snapshot of the current status of PA adoption is presented using available data on variable rate fertiliser management and yield mapping across regions... A snapshot of current adoption The results presented in Table 1 capture just two aspects of precision agriculture on a national scale that includes 5 selected SA regions (see report cited below for further details)...

"We have developed an economic calculator to calculate the profit from using a zone-management system for fertiliser application within a paddock, compared with using a uniform rate over the whole paddock," he says... The calculator takes into account relative areas of zones within a paddock, yield differences between zones, soil nutrient levels between zones and the prices of grain and fertiliser... "Based on the potential yields of different zones in a paddock, it will generate an optimal fertiliser recommendation for each of those zones," Dr Lawes says...
